1\dfrac{7}{10}+3\dfrac{13}{20}

Method 1.

Find LCM of denominators:

LCM(10, 20) = 20

1\dfrac{7\cdot2}{10\cdot2}+3\dfrac{13}{20}=1\dfrac{14}{20}+3\dfrac{13}{20}=(1+3)+\left(\dfrac{14+13}{20}\right)=4\dfrac{27}{20}=4\dfrac{20+7}{20}=5\dfrac{7}{20}

Method 2.

Convert mixed numbers to decimal:

1\dfrac{7}{10}=1.7\\\\3\dfrac{13}{20}=3\dfrac{13\cdot5}{20\cdot5}=3\dfrac{65}{100}=3.65\\\\1\dfrac{7}{10}+3\dfrac{13}{20}=1.7+3.65=5.35

The sum of three consecutive even numbers is 96. What is the smallest of the three numbers
lidiya [134]
The answer is 30.

First off, the numbers are consecutive even numbers. So, the difference between every consecutive number is 2 (numbers go from even to odd to even to odd...). Since the sum of their numbers is 96, I divided that by 3 to get 32. This gives me the median of the three numbers. To find the smallest number, I simply subtracted 2 from the 32.


This may help:

96/3=32

32 + 32 + 32 = 96
(32-2)+(32+0)+(32+2)=96
30+32+34=93

Can someone help me with this ONE question? Write an equation.. and solve for X
matrenka [14]

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.
